Elias Naur b47653b808 gpu/internal/metal: don't double-buffer staging memory
One staging buffer is enough because BeginFrame waits for the completion
of the staging operatoins from the previous frame.

Elias Naur c9970cb8e3 gpu,gpu/internal,internal/gl: replace BlitFramebuffer with CopyTexture
OpenGL ES 2.0 doesn't support glBlitFramebuffer, but does support
glCopyTexSubImage2D. Fortunately, we don't need the extra features of
glBlitFramebuffer anyway.

Elias Naur 3b2992c37e gpu,app/internal/wm: add Metal port

replacement, the Metal GPU API.
